On the surface, it is a high-end salon, but behind the scenes, they use suspicious substances to immerse beautiful women one after another in pleasure and sell them overseas. Detective Serina hears information that there are people running such a shady business and tries to infiltrate. However, the information is leaked and she is caught by the thugs. And, to make matters worse, the thugs inject a suspicious substance (aphrodisiac) into her neck. From here, the thugs begin to torture her with pleasure! Serina tries her best to act tough, but a pleasure she has never felt before runs through her body and she falls in an instant. At first, she looks embarrassed, but by the end, she climaxes many times, shaking her hair and screaming, "I'm cumming! I'm cumming!". She then looks as if she is begging for forgiveness and pleads, "I'm cumming! I'm cumming!" However, the men's pleasure torture did not ease up, but rather became more intense with each insult, and before she knew it, her eyes were Serina in the wrong direction and her body was trembling violently.
